>>4475651Just remember that the process requires a mobile darkroom if you plan on going out of a studio to photograph stuff. You can make one pretty easily by using a red glass pane glued on top of a light tight darkroom box that you work in. The sun gets filtered into safelight you can use to work under. Battery powered redlight may also work well, but you'll find that you may be working a single scene for a few hours. There's a lot of trial and error involved in the process.
You'll also need a watertight/travel safe dip tank for sensitizing your plates. They're a bit more expensive, but work all around better than the cheaper dip tanks.
There is a very steep learning curve to the entire process, so you'll be stuck at home for a while getting a solid grasp on everything. Buy like 100 4x5 plates if you can. One thing to remember that fucked me a first. You MUST have good ventilation in your darkroom. If you don't your plates will fog. Took me many hours to figure that one out.
I think the folky vibe + wetplate would work really really well. Wetplate portraits are special, but you need a shitload of light for them.
